GUARD-RAIL.

Specification of Letters Patent.

Patented Mar. 16, 1915.,

Application filed March 9, 1914. Serial No. 823,437.

To all whom it may concern:

Be it knownthat I, HARRY E. DILLON, of Olean, in the county of Cattaraugus, in the State of New York, have invented new and useful Improvements in Guard-Rails, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in guard rails and more particularly to a concrete guard rail for roads, bridges, etc.

The primary object of the invention is to produce a guard rail of inexpensive construction which, by reason of its form and shape, shall have a maximum strength for the material used, and which may be susceptible of manufacture in sections and may be assembled at any desired place and the rails firmly, rigidly and removably attached to the supporting posts in a simple manner and without the necessity of skilled labor.

Having the above objects and uses in mind, my invention resides in the new and novel construction hereinafter described in connection with the accompanying drawings in which Figure l is an elevation of a portion of the completed guard rail of my invention. Fig. 2 is a view partially in cross section of one of the posts and the rail supported thereby. Fig. 3 is a longitudinal section through a portion of two rails having their ends abutting, and showing the embedded attaching members. Fig. 4 is a top plan view of one of the supporting posts. Fig. 5 is a perspective view of a portion of a rail showing the reinforcement.

The invention comprises a supporting concrete post or posts 1 preferably reinforced in any suitable manner as by longitudinally disposed metal rods 2. This post as shown is circular in cross section and enlarged toward its base, but it is readily apparent that it may be of any form and size desired in connection with the particular use, or condition of use, to which it is put. The upper part of the post, either in the process of manufacture, or later in any suitable way, is formed with its side walls converging toward the top, leaving however a horizontally disposed portion of suitable width to support a plate 3 which is permanently attached to the post 1 by a king bolt 4 which is embedded in the post, and this plate -3- is provided, as shown, with suitable openings 5 for a purpose hereinafter described.

The rail sections -6- are of inverted trough shape and have a horizontally disposed portion -7 of a width suflicient to receive the plate 3- and diverging side walls -8 and 9 adapted to fit the converging walls of the top of the post, so that the rail will fit tightly over the top of the post. The angular disposition of the side walls 8- and 9 and the top of the post transfers the strain upon the rail 6 to the body of the post, rather than solely to the top of the post which is in contact with the rail, and preferably these rails are formed with cross walls or partitions 10- adapted to form a reinforcement for the rail.

The respective ends of each rail section 6- are provided with partially embedded bolts -1 preferably angular in cross section, decreasing to a minimum the liability of their being withdrawn from the rail, although they may be of any shape and size and are provided with a projecting threaded portion so disposed and arranged that when the ends of two rail sections are abutting over a supporting post these bolts register with the respective openings -5- in the plate 3- and are adapted to pass through these openings and may be firmly attached and tightened by suitable nuts l4, thus forming a rigid connection between the rails and posts.

The concrete rails 6 are preferably reinforced in the process of manufacture by any suitable means, as the expanded metal sheet 12 shown, which extends throughout the rail, or any other reinforcing means may be used or may be entirely omitted without departing from the other features of my invention as herein set forth.

Preferably, by reason of the uneven settling of the ground and therefore the posts and by reason of the heaving of the ground by frost, and for other reasons, each rail is made of suflicient length to extend between two posts only and these posts may be spaced apart any desired predetermined dis tance. However, in certain climates and under certain conditions, it may be desirable to make the rails 6- extend across a plurality of posts and I do not, therefore, limit myself to a two-point support for the rails, but they may be of any length and supported at as many points as desired, and likewise positioned above the ground 13- at any height desired.

It will be apparent that many changes may be made in the detail construction of the parts and in their formation and arrangement Without departing from the spirit of the invention as set forth in the appended claim.

What I claim is:

In a structure of the class described, a post formed of composition material and having a substantially fiat top and sidewalls diverging therefrom a member partially embedded in said post, a plate resting upon the flat top of said post, and secured Goplu of this patent may be obtained for thereto by said member, a rail formed of composition material and having a horizontally disposed portion and side-Walls diverging therefrom and adapted to fit over the top of the post, a member partially embedded in said rail and adapted to be remov-. ably engaged with said plate for removably securing the rail and posts together.

In Witness whereof I have hereunto set my hand this 21st day of February, 1914. HARRY E; DILLON.
